MLB Baseball Ratings

Below are listed the current MLB Baseball computer ratings as computed by the Donchess Inference Index. These ratings are updated about once a week during the season so check back early and often.
More information on how these MLB computer ratings are computed can be found on the Methodology page.

DII Rating– This is a MLB ratings system that is a combination of the Standard Rating and the Inference Rating. The Inference Rating is weighted more highly in the beginning of the season whereas the Standard Rating is weighted more highly at the end of the season. This is the final rating that is used to rank the teams.

Standard Rating– Looks at game outcome and score differential only. Record is the most important factor in this rating system.

Inference Rating– Heavily weights the outcomes of opponents’ games. This is system is a much better predictor of future game outcomes.

Vegas Rating– This is our newest rating that only takes into account the Vegas line on each game. More recent games are weighed the most heavily, but outcome and score differential are no factor at all. This rating system, combined with the Inference Rating, is a very good predictor of future outcomes.

We also do predictions on every game during the Major League Baseball season. For more information on this go to MLB Game Prediction.
